Focalin Side Effects: a Complete Review
Dexmethylphenidate, marketed as Focalin, is used to treat ADHD. Focalin XR is a stimulant that is taken orally and has an extended-release. It has been approved for ADHD treatment in children aged 6 to 12, adolescents, and adults. However, despite Focalin’s efficacy in treating attention deficit hyperactivity disorder, its usage has been associated with side effects. This article will get a complete review of Focalin’s side effects. So, let’s dive in!

How Does Focalin Make You Feel?
Focalin works by changing the number of certain substances in the brain. It is a Central nervous system(CNS) stimulant. It works by improving focus and alertness in ADHD patients. Because it is a CNS stimulant, it may cause alertness or wakefulness in the patients taking it. Although the precise mechanism of action is unknown, Focalin is thought to promote the effects of norepinephrine and dopamine in the brain. Low norepinephrine and dopamine levels may contribute to ADHD symptoms.
Is Focalin the Strongest ADHD Medication?
Dexmethylphenidate is the active component of methylphenidate, which is why Focalin is considered twice as strong as drugs like Ritalin and Concerta on an mg for mg basis. The concept underneath Focalin is that the dexmethylphenidate HCl isomer is more effective than the methylphenidate in medicine such as Ritalin while producing fewer side effects. Because of this distinction, Focalin is frequently prescribed at half the dose of Ritalin while providing equivalent therapeutic benefits.

Most Common Side Effects of Focalin
Focalin’s most common side effects are upset stomach (pain abdomen), elevated heart rate (tachycardia), raised blood pressure, dry mouth, and nausea. Stimulants can also cause appetite loss, which can lead to weight loss. Listed below are the most common side effects of Focalin;
- Abdominal pain
- Nausea
- Weight loss
- Palpitations
- Dizziness
- High blood pressure
- Migraine
- Dry mouth
- Disturb taste
- Headache
Focalin may also cause some psychological or emotional side effects. Focalin’s emotional side effects may include mood swings, aggression, suicidal thoughts, and agitation. Focalin’s side effects in adults and children may be the same. However, your child may experience minor headaches, tummy aches, or even nausea when starting a new medication. So, seek professional assistance from your doctor.

Long-term Side Effects of Focalin
Focalin is also habit-forming, which means that chronic use can cause physical drug dependence. Stimulant drugs interact with the brain’s chemical makeup and have a mind-altering impact. Therefore, the longer and more of the medication taken, the more significant dependence will be. The prescribing information for Focalin XR warns that the drug has a high risk of dependence. The following long-term side effects of Focalin can be observed when the drug wears off;
- Mood swings and depression
- Insomnia
- Fatigue
- Night terrors as well as vivid dreams
- Increased appetite
- Problems with coordination and motor control
Focalin Drug Interactions
Focalin has some drug interactions as well. For example, MAOIs, or monoamine oxidase inhibitors, can enhance the effects of CNS stimulants like Focalin. However, when MAOIs are combined with CNS stimulants, they can cause high blood pressure, also called hypertensive crisis, heart attack, and stroke. Therefore, Focalin should not be used in conjunction with MAOIs or within 14 days of discontinuing an MAOI. Focalin should be used with caution in people taking serotonergic medications such as antidepressants, lithium, fentanyl, and St. John’s wort when Focalin is combined with serotonergic drugs, the risk of serotonin syndrome, a potentially fatal condition, increases.
Because stimulants can cause an increase in blood pressure, the effects of blood pressure medications may be reduced. Therefore, if you are taking a stimulant and blood pressure medication, you may need to adjust your dosage. PPIs (proton pump inhibitors) may interfere with the absorption of Focalin. This may result in an increase or decrease in effects.
Wrap Up
Despite Focalin’s efficacy, patients should be aware that there is a risk of abuse with Focalin. This is particularly true if the individual has a history of substance abuse. Before using, discuss Focalin’s side effects and interactions with your doctor. Still, have any questions? Get in touch with certified professionals at MEDvidi to get the best telemedicine services.

Medicines for mental illness
The effectiveness of drug therapy with psychotropic drugs is determined by the compliance of the choice of the drug with the clinical picture of the disease, the correctness of its dosing regimen, the method of administration and the duration of the therapeutic course. As in any field of medicine, in psychiatry it is necessary to take into account the entire complex of drugs that the patient takes, since their mutual action can lead not only to a change in the nature of the effects of each of them, but also to the occurrence of undesirable consequences.
There are several approaches to the classification of psychotropic drugs. Table 1 shows the classification proposed by the WHO in 1990, adapted to include some domestic medicines.

The main clinical characteristics and side effects of the listed classes of pharmacological drugs are given below.
Antipsychotics
Clinical characteristics. This class of drugs is central to the treatment of psychoses. However, the scope of their application is not limited to this, since in small doses in combination with other psychotropic drugs they can be used in the treatment of affective disorders, anxiety-phobic, obsessive-compulsive and somatoform disorders, with decompensation of personality disorders.
Regardless of the characteristics of the chemical structure and mechanism of action, all drugs of this group have similar clinical properties: they have a pronounced antipsychotic effect, reduce psychomotor activity and reduce mental arousal, neurotropic effect, manifested in the development of extrapyramidal and vegetovascular disorders, many of they also have antiemetic properties .
Side effects. The main side effects in the treatment of neuroleptics form the neuroleptic syndrome. The leading clinical manifestations of this syndrome are extrapyramidal disorders with a predominance of either hypo- or hyperkinetic disorders. Hypokinetic disorders include drug-induced parkinsonism, manifested by increased muscle tone, lockjaw, rigidity, stiffness, and slowness of movement and speech. Hyperkinetic disturbances include tremor and hyperkinesis. Usually in the clinical picture in various combinations there are both hypo- and hyperkinetic disorders. The phenomena of dyskinesia can be paroxysmal in nature, localized in the mouth area and manifested by spasmodic contractions of the muscles of the pharynx, tongue, lips, jaws. Often there are phenomena of akathisia - feelings of restlessness, "restlessness in the legs", combined with tasikinesia (the need to move, change position). A special group of dyskinesias includes tardive dyskinesia, which occurs after 2-3 years of taking antipsychotics and is expressed in involuntary movements of the lips, tongue, face.
Among the disorders of the autonomic nervous system, orthostatic hypotension, sweating, weight gain, changes in appetite, constipation, diarrhea are most often observed. Sometimes there are anticholinergic effects - visual disturbances, dysuric phenomena. Possible functional disorders of the cardiovascular system with changes in the ECG in the form of an increase in the Q-T interval, a decrease in the T wave or its inversion, tachycardia or bradycardia. Sometimes there are side effects in the form of photosensitivity, dermatitis, skin pigmentation; skin allergic reactions are possible.
Antipsychotics of new generations, compared with traditional derivatives of phenothiazines and butyrophenones, cause significantly fewer side effects and complications.
Tranquilizers
Clinical characteristics. This group includes psychopharmacological agents that relieve anxiety, emotional tension, fear of non-psychotic origin, and facilitate the process of adaptation to stressful factors. Many of them have anticonvulsant and muscle relaxant properties. Their use in therapeutic doses does not cause significant changes in cognitive activity and perception. Many of the drugs in this group have a pronounced hypnotic effect and are used primarily as hypnotics. Unlike neuroleptics, tranquilizers do not have a pronounced antipsychotic activity and are used as an additional tool in the treatment of psychosis - to stop psychomotor agitation and correct the side effects of neuroleptics.
Side effects of during treatment with tranquilizers are most often manifested by daytime drowsiness, lethargy, muscle weakness, impaired concentration, short-term memory, as well as a slowdown in the speed of mental reactions. In some cases, paradoxical reactions develop in the form of anxiety, insomnia, psychomotor agitation, hallucinations. Among the dysfunctions of the autonomic nervous system and other organs and systems, hypotension, constipation, nausea, urinary retention or incontinence, decreased libido are noted. Long-term use of tranquilizers is dangerous due to the possibility of developing addiction to them, i.e. physical and mental dependence.
Antidepressants
Clinical characteristics. This class of drugs includes drugs that increase the pathological hypothymic effect, as well as reduce depression-related somatovegetative disorders. A growing body of scientific evidence now suggests that antidepressants are effective for phobic anxiety and obsessive-compulsive disorders. It is assumed that in these cases, not the actual antidepressant, but the anti-obsessional and antiphobic effects are realized. There is data confirming the ability of many antidepressants to increase the threshold of pain sensitivity, to have a preventive effect in migraine and vegetative crises.
Side effects. Side effects related to the central nervous system and the autonomic nervous system are expressed as dizziness, tremor, dysarthria, impaired consciousness in the form of delirium, epileptiform seizures. Possible exacerbation of anxious disorders, activation of suicidal tendencies, inversion of affect, drowsiness or, conversely, insomnia. Side effects may be manifested by hypotension, sinus tachycardia, arrhythmia, impaired atrioventricular conduction.
When taking tricyclic antidepressants, various anticholinergic effects are often observed, as well as an increase in appetite. With the simultaneous use of MAO inhibitors with food products containing tyramine or its precursor - tyrosine (cheeses, etc.), a "cheese effect" occurs, manifested by hypertension, hyperthermia, convulsions and sometimes leading to death.
When prescribing serotonin reuptake inhibitors (SSRIs) and reversible MAO-A inhibitors, there may be disturbances in the activity of the gastrointestinal tract, headaches, insomnia, anxiety, and impotence may develop against the background of SSRIs. In the case of a combination of SSRIs with drugs of the tricyclic group, the formation of the so-called serotonin syndrome, which is manifested by an increase in body temperature and signs of intoxication, is possible.
Normotimics
Clinical characteristics. Normotimics include drugs that regulate affective manifestations and have a preventive effect in phasic affective psychoses. Some of these drugs are anticonvulsants.
Side effects of when using lithium salts are most often tremor. Often there are violations of the function of the gastrointestinal tract - nausea, vomiting, loss of appetite, diarrhea. Often there is an increase in body weight, polydipsia, polyuria, hypothyroidism. Acne, maculo-papular rash, alopecia, as well as worsening of psoriasis are possible.
Signs of severe toxic conditions and overdose of the drug are a metallic taste in the mouth, thirst, severe tremor, dysarthria, ataxia; in these cases, the drug should be stopped immediately.
It should also be noted that side effects may be associated with non-compliance with the diet - a large intake of liquid, salt, smoked meats, cheeses.
Side effects of anticonvulsants are most often associated with functional disorders of the central nervous system and manifest as lethargy, drowsiness, ataxia. Hyperreflexia, myoclonus, tremor can be observed much less frequently. The severity of these phenomena is significantly reduced with a smooth increase in doses.
With a pronounced cardiotoxic effect, atrioventricular block may develop.
Nootropics
Clinical characteristics. Nootropics include drugs that can positively affect cognitive functions, stimulate learning, enhance memory processes, increase brain resistance to various adverse factors (in particular, to hypoxia) and extreme stress. However, they do not have a direct stimulating effect on mental activity, although in some cases they can cause anxiety and sleep disturbance.
Side effects - rare. Sometimes there are nervousness, irritability, elements of psychomotor agitation and disinhibition of drives, as well as anxiety and insomnia. Dizziness, headache, nausea and abdominal pain may occur.
Psychostimulants
Clinical characteristics. As the name of the class implies, it includes psychotropic drugs that increase the level of wakefulness, have a stimulating effect on mental and physical activity, temporarily increase mental and physical performance and endurance, reduce the feeling of fatigue and drowsiness.
Side effects of are mainly related to effects on the central nervous system (tremor, euphoria, insomnia, irritability, headaches, signs of psychomotor agitation) and the autonomic nervous system (sweating, dry mucous membranes, anorexia). In addition, there may be disorders of cardiovascular activity (arrhythmia, tachycardia, increased blood pressure), as well as a change in the body's sensitivity to insulin in patients with diabetes mellitus. Long-term and frequent use of stimulants can lead to the development of mental and physical dependence.
